Abstract
An electrophotographic element which comprises a conductive substrate and a photosensitive layer, superposed thereon, consisting of a charge generation layer and a charge transport layer, said charge transport layer containing as an available ingredient a hydrazone compound having the following general formula (I): ##STR1## (where R is a hydrogen atom, an alkyl group, of from one to six carbon atoms, an alkoxyl group of from one to six carbon atoms, a substituted or non-substituted dialkylamino group, halogen, a nitro group or a hydroxyl group. n is an integer of 1-5. In case where n is 2 or more, R may be the same or different.).
